Otherwise, not much else of concern out to 1.5MHz. Notice that even with the relatively low resolution of the Rigol FFT, we can see the images out to the 524+554kHz and 598+628kHz pairs. To see if we can correlate the oscilloscope's FFT with what I see using the RME ADC, here's what happens when we send a 0dBFS 24/384 150kHz signal to the SMSL iDEA: The oscilloscope is able to measure up to 100MHz which is beyond "ultrasound" of course. On screen: A 100kHz signal off the SMSL iDEA.
As a result, we can't expect detailed graphs, but it'll give us an idea if there are large amounts of noise out in the MHz range. Remember that the majority of these less expensive digital storage oscilloscopes provide only 8-bit resolution and are meant to be used on multi-MHz waveforms, not kilohertz audio. I don't have anything fancy for this but I do have a Rigol DS1104Z digital oscilloscope that can give me a low-resolution FFT to look above 384kHz and into the MHz frequencies.
SIN XTR HQPLAYER PRO
There’s another paid software called Acourate that can be a little complicated compared to Audiolense but perhaps more powerful in terms of features.Going beyond 384kHz bandwidth requires a different tool than the RME ADI-2 Pro FS. There is a guide on this forum and lots of Community help if you get stuck, that’s a big positive.
SIN XTR HQPLAYER FREE
You can also use free software like REW but that can be a little more complex. HQPlayer is the ‘convolver’ in this case. In Audiolense (for example) you can then specific a ‘target’ frequency response (and adjust impulse response if you want) to your liking.Īudiolense then spits out a couple of files that you import into HQplayer that will tell HQPlayer to make adjustments to your music on the fly - real-time adjustments to achieve the target response that you specified, by reducing levels of some frequencies and maybe boosting levels of some frequencies.
Typically you will measure at your listening position. In very simple terms, you can use a program like Audiolense (costs money) that will measure the speakers frequency response and impulse response, inside your room at the positions you place the microphone.
I wouldnt even know where to start with Convolution If you really do not hear a ‘qualifying’ difference, stick with PCM.Īnd again your HQPlayer settings are fine. But, aftert those couple of days, you will really start feeling that you are missing something, of at the contrary you have gained something. Than switch to the other setting.Īs it will sound different, you will believe in the first couple od days that the newer setting will sound bettter. Just listen to your equipment with 1 fix choice for at least 1 month. The only (big) advantage of PCM upsampling is that it needs far less computer power (and so less heat and eventually less noise if fans are involved) than DSD upsampling. My HQplayer settings are DSD256, poly-sing-xtr-lp, ASDM7.īut what is right for me is far from right for other people. I am personally a big fan of DSD, but I am sure I could live with PCM as well (although I might have bought another DAC than my T+A 8 DSD dac). Yoiur settings are excellent, but only your ears can tell you what you actually prefer with your DAC: SDM (DSD256) and PCM (768Khz).
